The invention relates to devices for use in the fuel intake passages of internal combustion Vengines for the purpose of effecting a.Y

thorough mixture of sprayed fuel and air.

The object of the invention is to provide a device of the class set forth which is extremely simple and inexpensive,fyet efhcient and reliable for not only insuring thorough mixing of the fuel and,- air, but for so whirlingl the mixture as to prevent itfrom clinging to Y the wall of the intake passage. Y

With the foregoing inview, theinvention resides in the novel subject matter hereinafter described and claimed, descriptionbeing accomplished by reference to the, accomstructed in accordance with our invention.

Y o Figs. 2 and 3 are side elevations lookingfin different directions.

Fig. 4 is an edge view showing the device of an intake'manifold, section. r

F ig. 5 is an the :latter being in enlarged detail sectional view i on line 5 5 of Fig.f1.

In the form of construction selected for illustration in the present application, a ring 10 is provided for reception in the lower end of an intake manifold 11V or in some other part of thefuel intake passage of a motor. In the construction shown, ring 10 is provided with an outstanding flange 12 to be clamped between the manifold 11 and the carbureter 13.` Secured to and projecting inwardly from ring 10, are al number of vheli- -cally pitched vanes 14,7one end-of eachvane being preferably secured in a slot 15in said ring. The other ends of the vanes preferably project beyond the Aring and are longitudinally curved to elfect forcible whirling of the-l air and fuel coming in Contact withthem. The ends of these vanes disposed ytoward the delivery end of the `manifold orthe like 11,

are each provided with a plu-rality of longitu-VVV dinal slits 16. Finely wovenrwire webbing 17 covers the sides 'of the vanes 14C which are presented toward 'the oncoming fuel and air,

Vand this webbing extends" across the slots 16.

Atone end, the webbing is lanchored to the Vof helically pitched vanes secured kto and 19 and clinched upon the webs. y

Theconstructionshown or a substantial equivalent thereof provides a device which.k will produce a'homogenous mixture of air and sprayed fuel and will prevent clinging of the fuel to the walls ofthe passage. .All of the vanes are preferably constructed as shown and described and mounted upon a ringsuohr Y as 10, butl it is possible that within the scope of the invention, r"analogous vanes could be theV mountedin some other manner within fuel intake passage;` v f We claim 1.
